Definitions

  • the invention relates to a front axle of a truck or bus Features according to the preamble of claim 1.
  • This object is according to the invention in a front axle of the generic type by providing a maintenance-free steering knuckle / steering knuckle bearing solved with features corresponding to the characterizing part of claim 1.
  • Needle bearings of the upper bearing in a cup-shaped sleeve is the bottom of each of the adjacent outer end face of the Kingpin covered, is effective any penetration of dirt and Water from the outside axially to the needle bearings and their running surfaces on the kingpin prevented.
  • the interior of the sleeve of the lower bearing preferably also the interior of the sleeve of the upper bearing point at least one sealing member is sealed towards the axle body, is also one radial penetration of dirt and water between the parallel contact surfaces of the axle beam and steering knuckle jaws effectively prevented.
  • the steerable, non-driven (not shown) wheels of the front axle are mounted on trunnions 1 of steering knuckles 2, which on the rigid axle body 3 are pivoted about kingpin 4.
  • On the steering knuckles 2 means, such as projections 5 with connection surfaces 6, are provided at suitable points, to which steering bodies are connected (not shown) with which the steering movement from the steering wheel of the vehicle indirectly to the steering knuckle 2 is transferable.
  • the rigid axle body 3 has an upper support surface at each of its two ends 7, a parallel lower support surface 8 and a perpendicular to this Through hole 9 in which a kingpin 4 with its central portion 10 is fitted.
  • the knuckle 2 has a mouth 11, the top bounded by a flat surface 12 and below by a surface 13 parallel thereto and into which the axle body 3 protrudes. Also in the steering knuckle 2 in the sections 14, 15 present on both sides of the mouth 11 axially to one another aligned and perpendicular to the surfaces 12, 13 bearing holes 16, 17 given, in their respective area the upper bearing 16 or lower Bearing point 17 for the upper pin portion 20 or lower therein Pin section 21 mounted kingpin 4 is arranged.
  • the two bearing points 18, 19 are each kingpin 2 or kingpin 4 designed according to the invention for maintenance-free operation and each have a particular Double row needle bearings 22 and 23 on an outer sleeve 24th or 25 is included, in the relevant bearing bore 16 or 17 of the steering knuckle 2 is adjusted.
  • Each of the two sleeves 24 and 25 is cup-shaped and covered with their Bottom 26 and 27, the adjacent stin surface 28 and 29 of the kingpin 4th
  • the steering knuckle 2 engages over the end with its mouth 11 Connection area of the axle body 3, this with its upper end face 7 in Is sliding contact with the upper boundary surface 17 of the mouth 11 and with it lower support surface 8 with the interposition of at least one axial tolerance compensating shim washer 30 and an axial plain bearing 31 (Fig. 2) or Axial roller bearing 32 (Fig. 1) and the bottom 33 of this bearing 31 and 32 receiving Extension 34 of the cup-shaped sleeve 25 of the lower bearing 19 the lower boundary surface 13 of the mouth 11 is supported on the steering knuckle 2.
  • the cup-shaped sleeve 24 of the upper bearing 18 is preferably in one piece Deep-drawn part made of sheet steel, so far at certain points necessary - post-machining.
  • the bottom 26 of this sleeve 24 is in Installation position to a certain extent, e.g. B. 1 to 2 mm, from the adjacent end face 28 of the kingpin 4 spaced, this distance by a on the top row of rollers of the needle bearing 22 and on the inside of the sleeve bottom 26 supporting spacer ring 35 is retained
  • the sleeve 25 of the lower bearing 19 is composed of two parts 39 and 40 composed.
  • the first cup-shaped part 39 with the bottom 27, one cylindrical wall 41 and extension 34 with bottom 33 and cylindrical Outer wall 42 is in one piece, preferably by a deep-drawn part made of sheet steel, realized that - if necessary - reworked at certain points is.
  • the bottom 27 of the sleeve 25, which is given on this first sleeve part 39, is in the installed position to a certain extent, e.g. B.
  • the second part of the Sleeve 25 is made of plastic, for example, but is preferably also made of Steel sheet formed by deep drawing sliding sleeve 40 formed with a cylindrical guide portion 44 with friction on the cylindrical outer wall 42 the extension 34 sits and can be moved along the same.
  • the axial sliding bearing 31 according to FIG. 2 on the other hand consists of a pressure ring 49 which is slidable on a bearing washer 50 and supported by this on the bearing ring disk 46.
  • the axle body 3 On the top of the respective bearing 31 or 32, the axle body 3 is interposed the at least one washer 30 is supported.
  • the interior of the sleeve 25 of the lower bearing 19 is towards the axle body 3, as shown, sealed.
  • a rubber lip seal 51 is provided, which the upper free edge of the cylindrical outer wall 42 of the extension 34 engages around the first part 39 of the sleeve 25 and with its sealing lips the interior the sleeve 25 and the axial sliding or roller bearing 31 or 32 to the Sealing ring 30 or the lower support surface 8 on the axle body 3 seals.
  • the other provided labyrinth seal is realized in that the upper free end area of the first part 39 of the sleeve 25 including the rubber lip seal 51 overlapped by the sliding sleeve 40 forming the second sleeve part and this with the upper end portion 61 of its cylindrical outer wall 52 is extended into the area of the knuckle jaw 11 and there in an annular groove 53 is immersed in the axle body 3, the lower support surface 8 axially undercut, is incorporated.
  • This annular groove 53 engages over the immersing one Edge area 61 of the sliding sleeve 40 inside, outside and at the front with such a distance, that there is an annular channel with a U cross section open at the bottom, that forms the sealing labyrinth.
  • a circumferential Ring projection 54 may be provided, which acts as a stop and with the lower axle support surface 8 cooperating the axial depth of penetration Sliding sleeve 40 limited in the annular groove 53.
  • the sliding sleeve 40 is used when mounting the steering knuckle 2 and steering knuckle pin 4 first brought into a preassembled position pushed down, in not yet immersed in the annular groove 53, but with its upper edge 61 is spaced a certain distance from the lower axle support surface 8. Thereby it is possible if the axial sliding or roller bearing 31 or 32 is in Final installation position, the tolerance-related gap between the top of the bearing and lower axle support surface 8 with a possibly made of several individual disks Compound fitting washer 30 to fill, the thickness of which the measured gap height results. At the end of the assembly work the sliding sleeve 40 is immersed in its labyrinth seal functional position in the annular groove 53, shifted.
  • the upper and lower bearings 18 and 19 each have their cup-shaped Sleeves 24 and 25 in the center of their bottom 26 and 27 a recess 55 or 56, to which a grease nipple can be attached, with a through hole 57 or 58 for the passage of the lubricant.
  • This introduction of lubricant takes place only once due to the maintenance-free storage of the invention after completing the steering knuckle on the axle beam 3.
  • the depressions 55, 56 are then closed by blind plugs 59 and 60, respectively.
